E-Saver OPAL™ series maximizes savings. Compare each model’s optimized load range and the application for the most transformer energy savings.
Compare All transformer Models
All PDUs Come Standard with OPAL™ Series Transformers: Application Efficiency Optimized with Managed Inrush Currents.
|OPAL™ Transformer Models||Load Range & Application||Savings vs. DOE 2016*||Winding Material **||Continuos Overload Capacity||K-Rating ***|
Most light loads, feeding electronic equipment in schools, offices, commercial, institutional, applications
Widely varied equipment or process loading, or load changes overtime
|20%||CU||15%||K1, K9, K13|
High Equipment Loads- Pumps, elevators, etc. in labs, broadcast, datacenter, industrial etc
|25%||CU/AL, CU opt.||20%||K13|
Harmonic Mitigation for heavy harmonic-rich loads with high densities of electronic equipment
Heavy loads for extended hours. Process equipment, labs, broadcast, telecom, and some data centers
|35%||CU/AL, CU opt.||33%||K20|
Close to full continuous load. Labs, broadcast, telecom, and data centers, where overload capacity adds value, and energy rates and cooling costs are elevated
Solar Applications – operating from full load for long hours to idling at night
|30%||CU/AL, CU opt.||20%||K20 but not required|
* Estimated average energy savings for each load profile vs. DOE 2016 minimum efficiency rated transformer
**CU=Copper, CU/AL=Copper Primary with Aluminum Secondary
***K-Rating per IEEE-C57.110. The high K-factor rating is not the goal of the design, but a consequence of the low current densities used to achieve the high loading efficiency goals.
